Beit known that I, CHAsTIAN TAURMAN, a citizen of the-,United States, residing at Pikesville, in the county of `Baltimore and Stateof i Maryland, `have invented new-and useful Improvements in Beds, of which the following is a specification.

This invention relates to beds, andparticularly to the bottoms `or springs thereof.

Man'y devices have heretofore been constructed for adjusting spring bed-bottoms to` i' regulate and preserve the desired tension ofn the same and to compensate for irregularity of Weight-pressure on dierent portions, of

the same; but usually. these` devices have been more or less` complex, inconvenient in adjustment, and difficult to manage by ordinary persons unskilled in the art of mechanics. Furthermore, devices for adjusting spring bed-bottoms as heretofore employed have required the application of considerable power or force Vthereto in varying or` changing the` adjustmennand also the adjustment of bed-bottoms in independent parts has not been successful.

The present improvement has been devised for conveniently adjusting independent sections of a bed-bottom, so that a uniformity of tension may be obtained in all the sections,l or either of the sections may be adjusted to a greater or less tension than the others or all of the sections be uniformly stretched and a similar degree of resiliency maintained throughouti the entire bed-bottom.

Affurtherpurposeof the present improvement is to adjust either one of the sections of the bed-bottom independently of the others to rectify any sagging irregularity therein,` and thus constantlyp-reserve a uniformity of tension throughout the entire bed-bottom.

A further purpose of the present improvement is to simplifythe operating mechanism for stretching the several sections of the bedbottom, so that by the application of a minimum amount of power the result sought can be readily `consummated,`and, moreover, to have the stretching force applied to all the sections at one end of the bed-bottom and to pull the several sections in the same direction.

With these and other objects and advantages in View the invention consists `in the construction and arrangement of the several `proved device.

parts, which Will be morefully hereinafter described and claimed. 1

In the drawings, Figure lis a top plan View of a bed-bottom embodying the features of the invention. cal section on the line 2 2, Fig. l, showing part of the mechanism broken away. Fig. 3 is a side elevation of one extremity of the im- Fig. 4 is a longitudinal vertical section on the line 44, Fig. l. Fig. 5 is a side elevation of the opposite end. eX-. tremity at which the operating mechanism is located. Fig. 6 is a longitudinal vertical section on the line o 6, Fig. l.

The numeral 1 designates `a bed-bottom `comprising the ordinary side and end' bars `feature ofthe improved spring-Wire web is that each of the sections 3, 4, andu is independently adjustable, so that either of said sections may be stretched alone to compensate for some irregularity therein in relation to the other sections, and thereby constantly preserve an equal resilient tension in all the sections irrespective of a greater Weight-pressure that may be brought to bea-r upon a portion of the same.

The operating mechanism for all three sections is located solely at one end of the bed- 4 bottom and at that' end opposite the location of the end bar 6, and in the opposite side bars at the latter end the several components of the operating mechanism are operatively disposed. Extending through one side bar isa tubular shaft 7, which is rotatable and has its opposite end located within the opposing side bar, butdoes not extend through `the latter side bar. The end of the shaft 7 passing through the one side bar is terminally formed with an angular turn-head 8 and anadjacent ratchet 9, which is engaged by a paWl. 10, movably attached to an adjacent` portion of the side bar. On the shaft 7 a sleeve 11 is ro.- tatably mounted and has the section 3 of the spring-Web secured thereto, the said sleeve 11 being rotatable independently of the shaft Fig. 2 is a transverse verti- IOO 7 and formed with an angular turning-face 12 land a ratchet 13,engaged bya pawl14. The intermediate portion'of the shaft 7 has a sleeve 1'5 secured thereto and revoluble therewith, and to said sleeve the intermediate web-section 4 isattached by fastenings 16, which pass entirely through the sleeve 15 and shaft 7, as clearly shown by Fig. 2. On the opposite eX- tremity of the shaft 7 a sleeve 17 is rotatably mounted and projects through the side bar of the bed-bottom opposite that through which the shaft 7 extends and is formed with an outer angular turn-head 18 and an adjacent ratchet 19, engaged by a pawl 20. The Websection 5 is secured to the sleeve 17, and as a matter of convenience the ends of all the Websections are secured. respectively, to the sleeves 11, 15, and 17 by concave strips 21, applied over the section and coperating with ribs on the said sleeves, as clearly shown by Fig. 6.

In adjusting the several web-sections 3, 4, and 5 they are wound or unwound from the several sleeves 11, 15', and 17, and it will be seen that by revolving the shaft 17lhrough the medium of a suitable implement applied to the turn-head 18 thereof the central sleeve 15 will be similarly revolved and controlthe adjustment of the intermediate web-section 4. By turning the sleeve 11 on the shaft 7 through the medium of the angular face 12 the Websection 3 will be acted upon, and by turning the sleeve 17 the tension of the Websection 5 may be regulated. The tension of the several web-sectionswill be maintained by the pawls 10, 14, and 20, respectively engaging the ratchets 9, 13, and 19, and it will be understood that if it is desired to slacken the several sections said pawls may be thrown web-sections the latter can be stretched and the tension thereon institu ted, as maybe desired.

From the foregoing it will be observed that the several web-sections may be independently adjusted and caused to compensate for irregularities that may arise from time to time in the tension of the individual sections, so as to have all of the sections uniformly of the same tension, or, if necessity requires, one section may be tightened to a degree in excess of the remaining sections to secure some irregularity or compensate for an unequal disposition of weight-pressure upon different portions of the complete web.

The improved bed-bottom will be found exceptionally convenient, and the desire of the user in regard to a tight or slack spring can be accommodated with ease and facility.

Though the preferred construction has been shown and described, it will be understood that the same is but one embodiment of the salient feature of the invention, and it is proposed to adopt such changes and variations as may fairly fall within the scope and principle involved.

Having thus described the invention, what is claimed as new is A bed-bottom comprising a series of independently-movable resilient sections, a shaft .extending transversely across one end of the bottom and having a sleeve rotatable tl1erewith and to which the intermediate section is secured, other sleeves independently rotatable on the said shaft and having the remaining sections individually secured thereto, and means for individually and independently operating the said sleeves.

In testimony whereof I affix my signature in presence of two witnesses.
